'Devotion' in the Bible

So when they had finished breakfast, Jesus said to Simon Peter, “Simon, son of John, do you love Me more than these [others do—with total commitment and devotion]?” He said to Him, “Yes, Lord; You know that I love You [with a deep, personal affection, as for a close friend].” Jesus said to him, “Feed My lambs.”

Again He said to him a second time, “Simon, son of John, do you love Me [with total commitment and devotion]?” He said to Him, “Yes, Lord; You know that I love You [with a deep, personal affection, as for a close friend].” Jesus said to him, “Shepherd My sheep.”
